I know that the développement of PySide for that version of Qt is stopped, but for some cases, I want to install it.
Where can I download the last developped version of PySide for Qt 5.x ?
What you need is PySide2.
This wiki page tracks the progress of PySide for Qt 5.x development and provides further information concerning the effort:
http://wiki.qt.io/PySide2?
If you want to install it on anaconda:
conda install pyside2

I'm using QtCreator.
I have the following error. I'm using Pyside 6 and Qt 6.3.1 and Python 3.10
I tried to reinstall the whole qt maintenance tool and still nothing.
Can You guys help me?
You should install this module separately from Maintenance Tool.
I'm new to QT and QML, I found a cool KDE Plasma addon on the internet and wanted to edit it, but flushMode property, which I want to use, was introduced in QT 5.13. I have installed QT 5.15 (to be exact, 5.15.3), rebooted and got file:///filename.qml:58:2: "VideoOutput.flushMode" is not available in QtMultimedia 5.8. I also checked that qt5-multimedia is 5.15.3+kde+r0-1 (latest from arch linux repository), checked the QT version in system settings, everything says it's 5.15, but in the logs it acts like it's 5.8. Is it possible that I have 2 different qt5 installations, or why does this happen?
Yes, you very likely have two Qt installed. You got system Qt package that comes with desktop environment, I believe it does not include development files (headers), to obtain them you installed qt-something-dev package that installed another Qt as dependency.
I installed qt and qmake is using Qt version on 5.5.1.
qmake -v
version 3.0
Using Qt version 5.5.1 in /usr/lib/x86_64-linux-gnu
so how can i update qt version on ubuntu 16 to 5.7.
It appears that the most recent version available in the repo is 5.5.1.
So the way to go would be to just go to the Qt site and download either the online or the offline installer. You can also get the source and build it yourself, but that's rather slow and not recommended unless you actually need a custom build.
The installer will also give you a maintenance tool you can use to add or remove features and update in the future.
I got quite desperate on this, because I cannot install the open source Qt5 after I installed commercial Qt5 on my laptop.
This issue happened like this: My first trial of install Qt5, I chose the commercial license. Then when I tried to install PyQt5, it said my Qt5 license is commercial, not compatible with PyQt5 license. So naturally, as a open source lover, I uninstalled the Qt5. And reinstalled an open source version. But, no matter how many times I tried, PyQt5 says my Qt5 is still commercial license.
Dose anyone encounter the same issue here? And how did you solve it?
(I guess my last shot would be install a VM, but I sincerely hope I don't need to do that).

The issues turns out to be PyQt5 is not compatible with the newest Qt 5.5.0 at the moment. Choose a older version of Qt.
A couple of days ago,when I install PyQt5 in osx(10.9.5) the same problem came to me.I install qt-opensource-mac-x64-clang-5.5.0.dmg,and when I install PyQt-gpl-5.5.tar.gz,it said that Qt5 license is commercial, not compatible with PyQt5 license.So i just remove the Qt5.5 by "rm -rf Qt5.5",then i install qt-opensource-mac-x64-clang-5.4.1.dmg,at last everything works Ok.I googled but din't find something useful.maybe pyqt5 din't support the latest Qt5's license,but Qt5 has GPL and LGPL,pyqt5 has GPL,it should worked...ok,just gussing,hope this will helpful
I've been working on a PySide project using Qt 4.8.5 for awhile. There's a bug with Qt 4.8.5 that I keep running into. After a bit of research, I found that the bug first appeared in Qt 4.8.0, but that it didn't exist in Qt 4.7.4. So I decided to try downgrading.
I went to http://download.qt-project.org/archive/qt/4.7/ and I downloaded and ran qt-win-opensource-4.7.4-vs2008.exe.
Afterwards, to check that I had actually downgraded, I tried this:
$ python
>>> import PySide.QtCore
>>> print(PySide.QtCore.__version__)
4.8.5
>>> print(PySide.QtCore.qVersion())
4.8.5
It appears that PySide is still using Qt 4.8.5 instead of Qt 4.7.4. Does anyone know how PySide determines which version of Qt to use when multiple are installed? I don't want to uninstall Qt 4.8.5, because my project already mostly works with it and I'm not certain that using Qt 4.7.4 will actually work better.
The PySide documentation says that PySide works with Qt versions 4.6, 4.7, and 4.8, so I don't think that should be the issue.
If it's important, I'm using a 64 bit version of Windows 7 and I do have Visual Studio 2008 installed.
If you want to use Qt 4.7.4, you need to build PySide against that version.
The version you downloaded is "bounded" to the 4.8 version.
However, you can download the 1.1.1 version of PySide, using Qt 4.7.4, from this link: http://download.qt-project.org/official_releases/pyside/
The Windows PySide distributions are stand alone with all Qt libs and utils embedded so it does not mattter which Qt you have installed in your system. Newest PySide 1.2.1 has Qt 4.8.5 embedded.
